EDWARD H. ROY, 0F LOUISVILLE, KENTUCKY.

Application iled May 13, 1921.

To all cli/10m t may concern.'

Be it known that I, EDWARD H. ROY, a citizen of the United States of America, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to refrigeration and has special reference to an improved ice box.

One important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide an improved form of ice box wherein the ice space will entirely surround the sides and top of the food receptacle, except for door space.

A third important object of the invention is the provision of an improved form of ice box wherein the walls of the food .receptacle are formed of thin heat conducting material so that'heat can readily pass from the food.

With the above and other objects in view, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings. and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and r Figure 1 is a perspective view of an ice box constructed in accordance with this invention.

Fig. 2 is a vertical median section through an ice box constructed in accordance with this invention. K

In carrying out the objects of the vinvention in the form herein'illustrated there is provided an outer casing which consists of inner and outer walls 10 and 11 arranged in spaced relation and held in such position by spacing blocks or members 12. The 'space between the walls 10 and 11 is filled with h some suitable heat insulating material such as sawdust, flax tow, charcoal or the like and, for convenience and economy in construction these inner and outer walls may be made of wood.

The invention is top filling ice box and to that end the top ofthe box is provided with a series of hatch- Ways .Closed by hatches 14 each of which .is

especially adapted for a-y REFRIGERATOR.

constructed withv spaced inner and' outer walls and is packed with heat insulating material similar to the casing. Covering the entire interior of the casing and the sides of the hatchways is a waterproof lining 15 which may be made of galvanized iron or the like. This lining not only prevents moisture from soaking into the wooden walls but also protects the casing and hatchways from being bruised and broken. For the same purposes the inner and side faces of the hatches 14 are provided with a metallic covering 16.

Within the casing and spaced from the side and top wall thereof is a food receptacle 17 formed of thin sheet material having a high degree of heat conductivity, galvanized iron or the like being preferably used for its heat conducting, waterproofing and non-rusting properties. Within this food receptacle is a supporting frame 18 which not only serves to hold the food receptacle against collapse but also forms a convenient means to carry hooks 19 for hanging meat or other articles.

Due to this construction there is a space between the receptacle and casing wherein broken ice, with or without salt. may be placed through the hatchways, and it will be noted that these hatchways are so positioned as to lie, in part, over the spaces between the side walls so that these spaces may be easily filled.

or the purpose of removing water from the ice space a drain pipe 2() having a valve 21 is provided and to afford access to the food receptacle a doorway is formed leading from the outside of the casing into the receptacle and is equipped with the usual door 22.

An ice box constructed in this manner not only cools food quickly and keeps it cool but is very more, as the ice is kept in a chamber entirely shut off from the food an inferior nonygienic grade of ice can be used with corresponding low cost of operation.

There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

provided economical of ice. Furthermadein the form and construction of the invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact vform herein shownrand described, but it is An ice box including an outer heat in-v sulating casing, an inner food receptacle having walls of 'thin heat conducting material, said receptacle being spaced from the sides and top of the casing to form an ice receiving space, access means from the eX- terior end'of the casing to the foodreceptacle and icespace and a supporting lattice frame ing thereof, said frame being lexposed to the interior of the food receptacle whereby to permit attachment of food supportinghooks. In ktestimony whereof I affix my signature.
